`while the ilup'uline, or lavoring-property of thehops,

shall be retained iu the fermentingheer, which result I accomplish byplacing immediately over the tuns or vats containing the fermentingbeer, an ice-chamber, against which the gases impinge, and, beingthereby condensed, are carried off, together with the melting ice,out-side of the refrigerator, anda `constant supply of fresh airadmitted to the fermentation-chamber, as Iwill further explain byreference to the drawings, in which- Figure l represents a sectionallelevation ot' my brewers refrigerator', showing the beer-vault,fermentation-chamber, and iee-chamber;

the ice-chamber, the under sideor ceiling, L, of this oor (see iig. 2)beiiig provided with hollow panels M M, 85e., having apertures N,against which the volatile gases arising from the fel-inenting beer(placedin vats in the chamber O) impiuge,aud, heilig condensed, areconducted in the' pipes P I outside ofthe refrigerator, for future use.

It is the freslrair conductor, forsnpplying the vatchamber with freshain-and v S is the vault, containing barrels, into which the heer, afterfermentation, is run.
